Rob,
I just wanted to confirm your
The NCDOT sent your office a letter dated August 26, 2008 that discussed a construction issue associated
with Bridge 311 over Lake Wheeler on SR 1379 (Penny Road) in Wake County A pre-existing pipe around
Station 22+00 to 22+50 Lt was filled in during construction of the project causing ponding of water in
the nearby location It was determined that re-establishing a conveyance in its previous location was
allowable under the Neuse River riparian buffer rule
The NCDOT hydraulics unit provided a revised permit drawing that deputed construction of a lateral
rip-rap lined v ditch (with 3 1 slopes) from 22+00 to 24+00 Lt The Division 5 survey party has
determined that the rip rap lined v ditch with either a 3 1 slope or 2 1 slope cannot be constructed
because of ROW and riparian buffer footprint limitations We proposed to install a 15 inch corrugated
metal pipe from 22+00 to 22+40 Lt, which will allow water to drain from the ponded area Additionally,
a 12 foot long rip rap pad will be installed at the outlet of the corrugated metal pipe
We feel that this design is appropriate and within falls the intent of previous discussions between the
NCDOT and your office The pipe structure only serves to convey the water from the ponded area The
rip rap pad at the outlet of the structure will serve to slow down runoff through the pipe prior to
entering Lake Wheeler The attached figure provides a sketch of what is proposed at the site There
will be no additional impacts to jurisdictional streams, wetlands or riparian buffers as a result of
this proposed activity
Please confirm your understanding and agreement of the issues addressed in this email Thank you again
in advance for your assistance on this project
